PCT No. PCT/DE94/00774 Sec. 371 Date Jan. 11, 1996 Sec. 102(e) Date Jan. 11, 1996 PCT Filed Jun. 28, 1994 PCT Pub. No. WO95/01884 PCT Pub. Date Jan. 19, 1995A drive apparatus for a hybrid electric/combustion powered vehicle having an internal combustion engine and a gear-shifting transmission unit. The drive apparatus includes a rotatable crank shaft operatively connectable to the internal combustion engine, and a rotatable transmission shaft operatively connectable to the gear-shifting transmission unit. The drive apparatus further comprises a movable annular rotor disposed annularly about the transmission shaft, the rotor including a permanent magnet for generating a magnetic field and an attachment mechanism for attaching the rotor to the transmission shaft so that torque can be transmitted between the rotor and the transmission shaft. The stationary annular stator is attachable to at least one of the internal combustion engine and the gear-shifting transmission unit and is disposed concentrically about and proximate the rotor in an electromagnetically interactive relation. The stator includes a conductive winding for electromagnetically interacting with the magnetic field of the rotor, the stator defining a continuous axial recess annularly therewithin. The drive apparatus includes only one clutch disposed at least partially within the continuous axial recess of the stator, the clutch including 2 coupling mechanism for selectively and frictionally coupling the crank shaft to the transmission shaft for torque transmission therebetween so that the clutch is switchable between an engaged position in which torque can be transmitted between the crankshaft and the transmission shaft and a disengaged position in which torque transmission between the crankshaft and the transmission shaft can be discontinued.
